Wastewater Treatment Technologies

Centre for Science and Environment (CSE) in collaboration with the Colombo based NGO, Lanka Rainwater Harvesting Forum (LRWHF) organised a four day training programme in Colombo on ‘Urban Rainwater Harvesting (URWH) and Decentralised Wastewater Treatment (DWWT) and Reuse’ for engineers, researchers and practitioners from various organisations in Sri Lanka, between December 11 to 14, 2012.

The centralised sewage treatment technologies have proven to be expensive, complex and are failing to cater to the total wastewater generated. The untreated/partially treated wastewater makes its way to the water body causing immense degradation of the ecosystem and the environmental health.
